Akuma have you actually played IJ4? If not, it's quite bad. I owned one for a while. Very stop and go. It's extremely cheap in that often you plung the ball, it goes around the back orbit, misses every pop bumper, straight down the middle. Ball saver hits, auto plung the ball, same thing, onto bonus without ever hitting the ball. The shots to everything else tend to stop the bal for a boring animation. The ramp is way back so if you get a shot that is partially up it (happens often) the ball flies back down straight down the middle. The only cool thing is the arc and 8 ball multiball from it. I really wanted to like this game. I sold mine in a week. Found I was angry after playing it and hardly ever had fun.
I'm not trying to hijack your thread. But you indicated there aren't any around to play. So I suggest you play it a bit before making the trade.
